To all 'aU/wm t may concern.'

Be it known that l JOHN K. OELSLAGER,

' tains to make and use the same.

This invention relates to tank heaters, and the primary object of theinvention is to provide an improved means for shaking' grates,` so as topermit the ashes to be readily dislodged therefrom.

Another object of the invention is to provide an improved means formounting the shaker rod in the tank heater so that the same may bequickly and readily removed therefrom when so desired.

A further object of the invention is to provide an improved tank heaterhaving an inclined chute for permitting the ashes to be readily removedfrom the heater, the shaker being mounted in an offset guide way formedin the chute, so as not to interfere with the removal of ashes from theyheater.

A further object of theinvention is to provide an improved tank heaterhaving the upper portion thereof so formed, that the entire heater canbe immersed in the water in the tank, so that a maximum amount of heatradiating surface may be engaged by the\water.

A still further object of the invention is to provide an improved tankheater of the above character which is durable and eflicient in use, onethat is simple and easy to manufacture, and one that can be placed uponthe market at av reasonable cost.

With these and other objects in view the invention consists in the novelconstruction, arrangement and formation of parts, as will be hereinaftermore specificallv described, claimed and illustrated in the accompanvingdrawings, forming a part thereof, in Which:

Figure 1 is a vertical longitudinal section through the improved tankheater.

. Fig. 2 is a section taken on the line 22 of Fig. l.

Fig. 3 is a detail vie-w of'the shaker rod. Fig. 4 is a detail sectiontaken on the line H of Fig. 1.

Referring to the drawings in detail, wherein similar referencecharacters designate corresponding parts throughout the several views,the numeral 1 indicates the improved tank heater which includes' thebody 2 having the upper cylindrical portion 3 and the lowersubstantially rectangular portion 4, which forms the ash pit. The upperend of the body 2 is dome-shaped and provided with a smoke outlet 5. Anannular flange 6 is formed around the smoke outlet and receives anordinary stove pipe 7 having a damper 8 formed therein. An inner ange 9is formed on the inner surface of the body 2 intermediate thecylindrical portion 3 and the rectangular portion 4 thereof, and thefiange receives the grate 10 yand forms means for permitting the grateto be moved. An inwardly extending pin 11 is carried by the body 2 andengages the upper surface of the grate at the rear end thereof andprevents accidental displacement of the grate. The grate 10 is providedwith a radially extending lug 12, which is formed diametrically oppositethe pin 11 and this lug extends outwardly of the body 2 into theinclined chute 18, which extends upwardly and outwardly from the lowerportion i of the body and this chute communicates with the ash pit andforms means whereby the ash pan 14 may be readily removed therefrom. Thelug 9 is bifurcatedas at 12 for receiving the lower end of the shakerrod 15, which will be hereinafter more fully described.

The rear wall of the chute 13 is provided with an outwardly extendingoffset portion 16, which forms a guideway for receiving the shaker rod15 and also forms means whereby the shaker rod is positioned in rear ofthe inner face of the rear wall, so that the ash pan may be readilyremoved without contacting with the shaker rod or the lug 12. Asupporting plate 17 extends transversely across the guideway 16 adjacentto the lower end thereof and is spaced from the rear wall of theguideway, and the upper edge thereof is provided with an inwardlyextending notch 18, which receives the cylindrical bearing lug 19 formedon the shaker rod and this plate forms means for holding the shaker rodin correct operative position and permits the same to be readilyoscillated for shaking the grate.

The shaker rod 15 has the lower end thereof inclined upwardly, as at 20,and gradually tapered toward the end thereof so as to permit the same tobe readily inserted in the bifurcated portion of the lug 12. The shakerrod 15 is slightly enlarged adjacent to the inclined end and thecylindrical bearing 19 is formed on this portion. The inclined end 2O ofthe shaker rod conforms to the conguration of the lower portion of themeeting surface of the cylindrical body 3 and the offset enlargement 16.The upper portion of the shaker rod 15 forms an operating handle wherebythe same may be readily grasp ed so that it can be swung on thesupporting plate 17 and shake the grate. The upper end of the shaker rod15 ends adjacent to the upper end of the chute and in a convenientposition whereby the same may be readily grasped.

A removable cap 21 is provided for the upper open end of the chute 13and the cap is provided with a reduced extension 22 for engaging theoffset enlargement 16. The cap is provided with a pair of draft openings28, and a slide plate 23 is mounted in the guideway 24 formed on theupper edge of the cap 21 and this slide has a pair of openings 21 formedtherein which are adapted to register with the openings formed in thecap 21 when the plate is operated, so as to permit the entrance of airinto the chute and below the grate when so desired. The movement of theslide 23 is limitedin the guide way` 24, by means of a depending pin 27carried by the slide, which is slidably received in a slot 28 formed inthe cap 21.

An angular chute 25 communicates with the body 2 adjacent to the upperend thereof and a suitable cover 26 is provided for the same. rIhe chuteprovides means whereby `fuel maybe fed into the heater.

As clearly shown in Fig. 1 of the drawings the heater is to be placeddirectly in the tank which is to be heated, so that the water thereinmay readily circulate around the outer surface of the heater.

From the foregoing description it can be seen that an improved means isprovided for operating the grate which is so positioned in relation tothe ash removing ehute, that the same does not interfere in any waywhatsoever with the removal of the ashes.

In practice, I have found that the forni of my invention illustrated inthe accompanying drawings and referred to in the above description, asthe preferred embodiment7 is the most efficient and practical; yetrealizing the conditions concurrent with the adoption of my device willnecessarily vary, I desire to emphasize that various minor changes indetails of construction, proportion and arrangement of parts may beresorted to, when required without sacrificing any of the advantages ofmy invention as set forth.

/Vhat I claim as new is:

A tank heater comprising a body, a grate rotatably mounted in the body,an ash pit arranged below the grate, an outlet pipe communicating withthe upper portion of the body, an inclined chute extending upwardly fromand communicating with the ash pit, a cover for this chute, alongitudinally extending offset formed on the rear wall of the chute,and a rearwardly extending bifurcated lug formed on the grate andextending into the offset portion of the chute, a transversely extendingplate secured in the oifset portion and spaced from the rear Wallthereof, and a shaker rod arranged to be positioned in the offsetportion of the chute, the lower end of said rod being tapered andarranged to detachably ft in the bifurcated portion of said lug, and acylindrical bearing pin formed on said shaker rod adjacent to the lowerend thereof and arranged to detachably fit in said notch, as and for thepurpose specified.

In testimony whereof I aix my signature in presence of two witnesses.
